*Trichomonas vaginalis might be the causative microorganism in chorioamnionitis, particularly in young and sexually active patients.
Common causative pathogens could be further divided based on the clinical outcome


==Causes==
*Certain microorganisms which might be seen in patients with spontaneous preterm labor (intact membranes):
It is polymicrobial infection with two or more organisms involved:
**Fusobacterium nucleatum
* [[Bacteroides]] sp., especially Prevotella bivius
**Sneathia sanguinegens
* [[Streptococcus]] sp. (Groups A, B)
**[[Ureaplasma urealyticum]]
* [[Enterobacteriaceae]]
**[[Streptococcus mitis]]
* [[Chlamydia trachomatis]]
**[[Gardnerella vaginalis]]
* [[Ureaplasma urealyticum]].
**[[Peptostreptococcus]]
*Viruses ([[adenoviruse]] has be associated with hisological inflammation.
**Leptotrichia amnionii
*Fungi especially [[candidia]] in certain cases like ''in vitro'' fertilizationn, intrautrine devices and amniocentesis.
**Mycoplasma hominis
**[[Streptococcus agalactiae]]
**Lactobacillus species
**Bacillus species
**Coagulase-negative Staphylococcus species
**Prevotella species
